I RAIL OILER.

Application filed January13, 1927. Serial No. 160,895. I

This invention relates ,to a device designed for use in connection with railway rolling stock, and aims to provide means whereby a quantity of lubricating fluid may be deposited on the rails of a curved portion on a railway track to reduce friction between the flanges of the car wheels and rails to the minimum. 7

Another object of the invention isto provide a device of this character including a cylinder, a piston operating in the cylinder, a head on the cylinder and a valve member operating in the head to control the passage of steam or air to'the cylinder to operate the piston to force the lubricating liquid from the cylinder.

A still further object of the invention is to provide means including a valve for. directing steam to themlischarge nozzles of the device, when the device isinactive or in its normal position.

lVith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention@ Referring to the drawings;

Figure 1 is a vertical sectional view through a device constructed in accordance with the invention, on line'1-1 of Figure 2. a

Figure 2 is a sectional view taken on line 22 of Figure 1.

Figure 3 is aplan view of the device, the valve and cover thereof, being removed.

Figure 4 is a sectional view taken on line H of Figure 3.

Figure 5 is a valve.

Figure 6 is a diagrammatic view illustrating the automatic valve operating mechanism.

Referring to the drawings in detail, the device is indicated generally by the refer ence character 5 and is in the: form of a cylinder having discharge openings adja cent to the bottom thereof, and in which the pipe sections 6 are positioned, the pipe sections 6 being supplied with check valves 7 that operate to permit liquid to pass from the cylinder, but prevent the steam passing bottom plan view of the through the discharge pipes from entering the cylinder, at the base thereof. At the upper end of the cylinder is a flanges that provides a seat forthe head 9 which is formed with openings to accommodate securing bolts 10 that also pass through openings in the cap 11 to secure the cap in position. Y i I This head 9 is provided with a plurality of openings 11, which are arranged in predetermined spaced relation with each other and which openings establish communication between the interior of the cylinder and certain ports of the valve member to be hereinafter more fully described. i

The head'is also provided with an opening 12 which establishes communication between a bore 13, formed in the head and disposed. transversely thereof, which bore also communicates with the exhaust steam pipes '14 that extend downwardly and connect with the discharge pipes 15 that carry nozzles 16 on the depending free ends 1? thereof. 7 As shown,these nozzles 16 are so supported that they will direct fluid onto the inner, surfaces of the treads of rails at a curve on a railway track, to reduce the friction-betweenthe flanges of the wheels and rails over which they are passing.

The valve that operates to control the passage of steam or air to and from the cylinder is indicatedby the reference character 18 and moves-within the cap '11, the size of the cap being-greater than the'thickness of the valve to define a chamber 19 an operating shaft 22 that connects with the valve, 18 and is supplied with an arm 23 at its outer end, which arm may be connected with a suitable operating lever such as shown at 24 in Figure 6, which operating lever may have one end thereof connected with the tank or tender, while the device, forming the essence of the invention, is supported by the eng ne of a train to the end that When above the valve which is filled with steam valve into registry to cause an operation of the device and lubricate the rails.

Due to the provision of the grooves 21 it will be obvious that only a, slight movement of one car with respect to the other car, or car on which the device is supported, is necessary, to cause the steam or air to pass to the cylinder. The valve is also supplied with grooves 25 radiating from the center thereof, there being provided transverse grooves 26 communicating therewith, which grooves are designed to be brought into registry with the openings 11 so that the steam or compressed air may pass outwardly thercthrough, the central portion of the valve or inner ends of the grooves 25 being in registry with the lateral passageway 27 formed in the head, the passageway allowing the steam or air within the cylinder to exhaust therefrom. v

Lubricating fluid is fed by gravity to the cylinder 5, through the pipe 28. to the end that normally the cylinder is filled with the lubricating fluid, there being provided a check valve 29 for preventing the fluid from being forced through pipe 28 when the pis-- ton moves downwardly.

The piston is indicated by the reference character 30 and is. normally held to the limit of its'upward movement by means of the coiled spring 31 that has its upper end seated in a pocket formed within the piston 80, while the lower end thereof rests on'tne bottom of the cvlinder 5 as shown by Figure 1. 7

While the device is shown and described as operated automatically, it is to be understood that the device maybe manually controlled by connecting a suit-able lever to the valve arm 23. It might be further stated that when the valve is in itsnormal position, the steam is passing through the pipes 1. In a device of the character described,

a cylinder adapted to be supported by railway rolling stock, pipes communicating with the cylinder for receiving oil from the cylinder, nozzles on the pipe for delivering oil to the rails of the track over which the roll ing stock is moving, a steam chamber above the cylinder, an automatically controlled valve operating within the steam chamber for controlling the passage of steam to the cylinder, and apiston operated by the pressure of the steam passing through the val-ye for forcing the oil from the cylinder and nozzles.

2. In a device of the character described, a cylinder for containing oil, pipes leading from the cylinder and through which the oil passes on discharging from the cylinder, a piston operating in the cylinder for forcing the oil from the cylinder, steam pipes communicating with the first mentioned pipes, a valve operating in the upper portion of the cylinder for controlling the passage of steam to the cylinder to force the piston through the cylinder, and eject the oil from the cylinder, and said valve adapted to normally lie in a position to admit steam to the pipes.

In testimony that'we claim the foregoing as our own, we have hereto affixed our signatures.
